RELAY.

SPECIFICATION forming part of' Letters Patent No. 789,769, dated May 16, 1905.

Application tiled July 5, 1904. Serial No. 215,276.

To a/ZZ whom, t 11m/y concern:

Be it known that I, JEssn SUMMuns, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Relays, of which the following is a specification.

rIhe object of my invention is to produce an improved relay construction, the device being IO especially applicable for use in connection with watchmans time-recorders, such as that shown in my pending application, No. 108,409, of which a portion of this application is a division.

The accompanying drawings illustrate my invention.

Figure 1 is a perspective View, and Eig. 2 a vertical medial section.

In the drawings, 10 indicates a suitable 2O base, preferably of insulating material, upon which the various parts are mounted. Rising from base 10 is a post 11, which forms a conducting' member, and to the upper end of which is pivoted aconducting-lever or first swinging member or arm 12, one end of which y is provided with an armature 18, to be acted upon by an electromagnct 14. The opposite end of lever 12 carries an insulating-linger 15, provided on its under face a short distance from the end of'lever 12 with a notch 16, adapted to receive a cross-bar 17, carried at the upper end of a vertical conducting-lever or second swinging member or arm 18, pivoted on a horizontal axis on the conductingstandard 19. Bar 17 of lever 18is also adapted to lie in a notch 20, formed in the adjacent end of lever 12. The lower end of lever 18 is provided with an armature 21, adapted to be acted upon by an electromagnct 22. Secured to the end of linger 15 is one end of a spring 23, the opposite end of which is secured to the lever 18, the arrangement being such that the single spring will act upon the two levers 12 and 18 in opposition to the action of the electromagnets 14 and 22, respectively, and such that lever 12 is urged downward onto bar 17'and bar 17 is urged inward into notch 20. Let into the under surface of the linger 15, between notch 16 and the end of lever 12, is aplate or terminal 30, to which may be attached a suitable conductor 31, the arrangement being such that conductor 31 and terminal 8O may form one side of a second circuit, the other side of which is composed in part of lever .18, this second circuit being distinguished, however, from the circuit composed in part of lever 18 and the lever 12.

In operation, with the parts in the position shown in Eig. 2, if magnet 14 be energized lever 12 will be swung so as to throw arm 15 60 away from bar 17, whereupon spring23 will urge bar 17 into the notch 20,and thus electrically connect lever 12 and 18. An energization of the magnet 22 will then swing lever 18 away from notch 2O and into notch 16, the 65 spring 23 holding lever 12 down upon the bar 17. As bar 17 is swung away from notch 2O toward the notch 16 it will wipe across terminal or plate 80, and thus momentarily close the circuit of which terminal 30 and con- 70 ductor 81 form a part.

I claim as my invention- 1. A relay consisting of a swingingmember 12 having an insulated portion, an electromagnct for operating said member in one direction, a second swinging member 18 adapted to engage said first member or the insulated portion thereof, an electromagnct for swinging said second swinging member 18 in one direction, and means for simultaneously moving either swinging member upon actuation of the other swinging member by its magnet.

2. A relay consisting of pivoted member 12 having an insulated end, electromagnct 14 8 5 for moving the same in one direction, arm 18 adapted to engage member 12 or the insulated extension of member 12, electromagnct 22 for moving said member 18 in one direction, and a spring 28 connecting the ends of said two 90 members, substantially as and for the purpose set forth.

3. A relay consisting of a swinging member 12 having an insulated portieri an electromagnct for operating said member in one direction, a second swinging member adapted 23 connecting the ends of said two members, and the terminal 30 carried by the insulated I5 end of member 12 but electrically separate from said member and in position to be wiped across by the member 18, substantially as and for the purpose set forth.

In witness whereotI l' have hereunto set my hand and seal, at Indianapolis, Indiana, this 15th day of June, A. D. 1904.
